  ruby-on-rails ruby ruby-on-rails-3 nokogiri rails-console
  I’m using Nokogiri in Rails 3.2.11 to do some screen scraping. I have this one very long method that when I copy and paste line by line into the rails console it runs flawlessly, but when I call it in the console form my model file, it breaks, sending this error: Nokogiri::CSS::SyntaxError: unexpected ‘$’ after ”Here’s the method (it’s 2, the first calls the second). Any help at all would be much appreciated:def self.recurse_craigs(add = ‘o’)years = “#{MIN_YR}%7C05%7C#{MIN_YR+1}%7C06%7C#{MIN_YR

  I’m trying to use y object in Rails 3.2.6/Ruby 1.9.3 console to get nicely formatted yaml output for an ActiveRecord object, but for some reason it isn’t working for me. I’ve used it in the past, but somewhere along the way it broke. I get the following output when I try:NameError: undefined local variable or method `yaml’ for main:Object

  For example, this is a rails console session. I use tab key to get all available methods of app. But many of them is not possible to call:irb(main):040:0> app.default app.default app.default_executable= app.default_locale app.default_scoped? app.default= app.default_external_encoding app.default_locale= app.default_scopes app.default_action app.default_external_encoding= app.default_lockfil

  ruby stack-trace rails-console pry
  I am using Ruby on Rails 4 on Ruby 1.9.3. When an error occurs during a rake task, I get a very nice stack trace. When however I do something in my rails console (pry) that triggers an exception, I only get to see the error message and the one line of code that triggered it (which most of the time is somewhere in the rails core).Is there a way to enable these stack dumps in the console?
